CROSS REFERENCES TO RELATED APPLICATIONS

This Application is a continuation of U.S. application Ser. No. 16/455,004 filed on Jun. 27, 2019, entitled “HEADS UP MASS NOTIFICATION”, the content of which is hereby incorporated by reference in its entirety.

BACKGROUND

Existing infrastructures may include numerous alarm notification devices that provide basic warnings (e.g., activating siren and/or flashing hazard light) to occupants of the infrastructures during occurrences of hazard (e.g., fire, intruder in the infrastructures, power outage, etc.). When the occupants receive the warnings from the alarm notification devices, they may evacuate the infrastructures via the nearest exits. However, the nearest exists may not be safe (e.g., origin of the fire, point of entry for the intruder, etc.). To properly and safely avoid the hazard, detailed warnings may be necessary. While the alarm notification devices may be pervasive, they are unable to provide the detailed warnings to the occupants. For example, the alarm notification devices may be able to alert the occupants of the presences of the hazard, but they are unable to guide the occupants away from the hazard. Although there exists dynamic notification devices, it may be prohibitively expensive and time-consuming to install enough dynamic notification devices throughout an infrastructure to ensure that most, if not all, occupants are able to access detailed warnings or instructions. Therefore, improvements in mass notification may be desirable.

DETAILED DESCRIPTION

According to aspects of the present disclosure, using message notification devices with existing alarm notification devices may create a live platform for mass notifications and instructions within a building. Aspects of the present disclosure may capitalize on the distributed notification devices. By relying on the live platform, occupants may remain vigilant and aware of their surroundings while following the safest and most up-to-date instructions based on the data being collected by the fire, security, and/or controls systems of the building. By constantly analyzing the environment throughout the entire building, the message notification devices may update and display the safest strategy for numerous emergency situations, tailored for every section of the building. In some implementations, the integrated notification devices may also provide visual aids and instructions for audible-impaired occupants. In some implementations, the integrated notification devices may also display non-emergency notifications such as public announcements, visual advertisements, videos, or other marketing collateral when the emergency mass notification system is not in use.

In some aspects, the integrated notification devices may allow an occupant to have a natural viewing angle to read the notifications while remaining aware of the situation in the surrounding areas. By projecting below, or around, an alarm notification device, the reading area projected by the integrated notification devices may be placed in the line-of-sight of the occupants. The message notification devices for retrofitting the alarm notification devices may conform to the National Fire Protection Association (NFPA) standard.

In certain aspects of the present disclosure, the message notification device may be integrated into the notification network or function as a smart home device that creates an “invisible” interface that only appears when needed, requested, or triggered. Alternatively, the message notification device may include a blank screen for projecting images and/or messages. The screen may display the projected images and/or messages. The message notification device may include LED projection for display and/or infra-red (IR) laser diode and sensor/detector to allow a user to interact with the settings. The IR maps the location of the fingers/hands of the users and processes the movements based on displayed content and modifiable settings.

Turning now to FIG. 1 , a top-view of an infrastructure 101 may illustrate an example of an environment 100 for mass notification. The environment 100 may include the infrastructure 101. The infrastructure may have a first staircase 102 (aka “East Staircase”) for ingress into and egress out of the infrastructure 101 and/or reaching different floors of the infrastructure 101. The infrastructure 101 may have an exit 104 (aka “North Exit”) for ingress into and egress out of the infrastructure 101. The infrastructure 101 may have a second staircase 106 (aka “West Staircase”) for ingress into and egress out of the infrastructure 101 and/or reaching different floors of the infrastructure 101. The environment 100 may include integrated notification devices 120 a-1 configured to receive notifications and display messages. The integrated notification devices 120 a-1 may be placed in compliance with one or more local or national standards, such as the NFPA standard.

In some implementations, the environment 100 may include a server 140 for receiving hazard information and/or transmitting messages to be displayed by the integrated notification devices 120 a-1. In some examples, the server 140 may be a standalone server or a fire panel. The server 140 may be communicatively coupled with a repository 150. The server 140 and/or the repository 150 may be local or remote. The server 140 may include a communication component 162 for receiving hazard information from fire and/or security control systems (not shown) associated with the infrastructure 101. The communication component 162 may transmit messages to be displayed by the integrated notification devices 120 a-1. The server 140 may include a hazard component 164 that analyzes one or more hazards that may occur within the infrastructure 101 and provides appropriate messages corresponding to the one or more hazards. The messages may be stored in the integrated notification devices 120 a-1 and selected by the server 140 depending on the analysis of the one or more hazards. Alternatively, the messages may be transmitted to the integrated notification devices 120 a-1 by the server 140. In one implementation, the server 140 may transmit the same message to the integrated notification devices 120 a-1. For example, the integrated notification devices 120 a-1 may display the same message among the integrated notification devices 120 a-1. In another implementation, the server 140 may transmit different messages to the integrated notification devices 120 a-1. In another example, a portion of the integrated notification devices 120 may display a first message and a different portion of the integrated notification devices 120 may display a second message different from the first message. The server 140 may include a direction component 164 that analyzes the location of any hazard and provides an appropriate escape route. In one example, the messages provided by the server 140 may include warnings and/or escape routes. The integrated notification devices 120 a-1 may be placed on the walls of the infrastructure 101. The integrated notification devices 120 a-1 may be placed at “eye level,” or between 5-9 feet above the floor.

In certain aspects of the present disclosure, the server 140 may analyze, control, store (in the repository 150), distribute, transmit, receiver, and/or relay the hazard information, transmitting messages, environmental data, or other information.

During an emergency, a hazard 110 may occur within the infrastructure 101. The hazard 110 may occur near (e.g., within 1 foot, 2 feet (ft), 3 ft, 5 ft, 10 ft, or more) the first staircase 102. The hazard 110 may include a fire (accidental or intentionally set), a security breach, an intruder, an active-shooter, a carbon monoxide leak, or other events that may cause harm to the occupants. Alternatively, the hazard 110 may include events that do not occur within a specific location within the infrastructure 101, such as an earthquake, severe weather, lockdowns, or other threatening or non-threatening events.

During the emergency, each of integrated notification devices 120 a-1 may display the same message or different messages based on the known hazard (e.g., hazard 110) to guide the occupants to safety. The messages may include the same recommendation or different recommendations to be taken by the occupants, the types of hazard detected, emergency contact information, recommended escape routes, directions to safe exits closest to the integrated notification devices 120 a-1, or other appropriate message to help the occupants in the emergency.

In one non-limiting example, a hazard detector 142 may transmit an indication of hazard to the server 140 associated with the hazard 110 occurring near the first staircase 102. The hazard detector 142 may be an optical smoke detector, a passive infra-red detector, an ionization smoke detector, a carbon-monoxide detector, an intrusion alarm, a water leak detector, or other detectors. In response, the hazard component 162 may analyze the hazard 110 and determine that the hazard 110 is a fire that renders the first staircase 102 inaccessible. The direction component 164 may determine escape routes 130, 132. The communication component 160 may transmit individualized or different messages to the integrated notification devices 120 a-1. For example, the communication component 160 of the server 140 may transmit a message (“Evacuate→North Exit”) to the integrated notification devices 120 a, 120 b, 120 c. The message, when projected onto the wall, recommends the occupants reading the message projected by the integrated notification devices 120 a, 120 b, 120 c to evacuate the infrastructure 101 (“Evacuate”), walk toward the right direction (“→”), and leave the infrastructure 101 via the North Exit (“North Exit,” or equivalently, the exit 104). The message may recommend the occupants to exit the infrastructure along the escape route 130.

In some examples, the communication component 160 of the server may transmit a message (“Evacuate←North Exit”) to the integrated notification devices 120 d, 120 e. The message, when projected onto the wall, recommends the occupants reading the messages projected by the integrated notification devices 120 d, 120 e to evacuate the infrastructure 101 (“Evacuate”), walk toward the right direction (“←”), and leave the infrastructure 101 via the North Exit (“North Exit,” or equivalently, the exit 104). The message may recommend the occupants to exit the infrastructure along the escape route 130.

In some examples, the direction component 164 may determine that the integrated notification device 120 e should not display the message (“Evacuate→East Staircase”) even though the integrated notification device 120 e is closer to the first staircase 102 (“East Staircase”) than the exit 104 (“North Exit”). If the integrated notification device 120 e displays the “Evacuate→East Staircase” message, occupants following the recommendation along a route 134 may be unable to evacuate the infrastructure 101 because the hazard 110 may obstruct the access to the first staircase 102 (“East Staircase”). Therefore, even though the integrated notification device 120 e is closer to the first staircase 102 (“East Staircase”) than the exit 104 (“North Exit”), the direction component 164 may determine that the message to be displayed by the integrated notification device 120 e is “Evacuate←North Exit.”

In some implementations, the communication component 160 of the server 140 may transmit messages to the integrated notification devices 120 f, 120 g, 120 h, 120 i, 120 j, 120 k, 120 l that recommend the occupants to evacuate along the escape route 132. For example, the messages displayed by the integrated notification devices 120 f, 120 g, 120 h, 120 i, 120 j, 120 k may be “Evacuate→West Staircase.” The message displayed by the integrated notification devices 120 l may be “Evacuate←West Staircase.”

In alternative implementations, the hazard 110 may include an active shooter is in the infrastructure 101. The hazard component 162 may determine that the recommendation is for the occupants to return to a nearest room and bar the door. The communication component 160 may send the message (“Return to Room Bar Door”) to be displayed by the integrated notification devices 120 a-1. Alternatively, if the location of a shooter is known, the message may identify the location of the shooter and/or provide an escape route.

In another instance, the hazard 110 may include a severe weather (e.g., tornado, typhoon, thunderstorm, etc.). The hazard component 162 may determine that the recommendation is for the occupants to stay indoor within the infrastructure. The communication component 160 may send the message (“Stay Indoor”) to be displayed by the integrated notification devices 120 a-1.

Referring to FIG. 2 , an example of the integrated notification device 120 may include a alarm notification device 200. The alarm notification device 200 may include a visual notification indicator 210 that provides visual notifications (e.g., strobe lights, flashing lights). The alarm notification device 200 may include a speaker 220 that broadcasts audio notifications. The integrated notification device 120 may display messages in a display area 230 near the integrated notification device 120, such as beneath the integrated notification device 120. In other implementations, the display area 230 may be to the left, right, or above the integrated notification device 120. The display area 230 may be a surface near the integrated notification device 120, such as a portion of a wall or a projector screen. A projector screen may include a wall-mounted or pull-down white or gray screen. In some implementations, the projector may project different patterns of light onto the display area (e.g., wall, screen) to display a message, one or more words, one or more shapes, one or more signs or symbols, or other patterns. In one example, the projector may display the message “Evacuate←North Exit,” which includes the words “Evacuate” and “North Exit,” and the symbol “←”.

According to some aspects, the integrated notification device 120 may display advertisements, public announcements, non-threatening messages, or other messages when the server 140 does not detect a hazardous event in the infrastructure 101.

Referring to FIG. 3 , a side view of a first implementation of the integrated notification device 120 may include a message notification device 300 placed behind the alarm notification device 200. The integrated notification device 120 may be mounted into a portion of a wall 232 or on a surface of the wall 232. The alarm notification device 200 may include a terminal block 250 for receiving electrical energy and/or communicating with the server 140 via an input link 316 and an output link 314. The input link 316 may include wired and/or wireless connections that provide direct current (DC) and/or alternating current (AC) electrical energy to the alarm notification device 200 through the terminal block 250. The input link 316 may include wired and/or wireless connections that provide downlink communication channels between the server 140 and the integrated notification device 120. The output link 314 may include wired and/or wireless connections that provide uplink communication channels between the server 140 and the integrated notification device 120.

In some implementations, the message notification device 300 may include a printed circuit assembly (PCA) 320. The PCA 320 may receive electrical energy and/or downlink communication via the retrofitted input link 312 connected with the terminal block 250. The PCA 320 may transmit uplink communication via the retrofitted output link 310 connected with the terminal block 250. The retrofitted output link 310 may be connected to the output link 314 through the terminal block 250. The retrofitted input link 312 may be connected to the input link 316 through the terminal block 250. In an aspect of the present disclosure, the message notification device 300 may rely on existing infrastructures and/or hardware associated with the traditional notification tool 200 to communicate with the server 140 and/or receive electrical energy.

In certain aspects of the present disclosure, the message notification device 900 may include a detector 370 that detects motion at least in the display area 230. The detector 370 may include an IR diode and sensor that tracks motions of the occupant's body, such as fingers. The detector 370 may include one or more photodetector that captures images of the occupant's body (e.g., fingers) and perform image analysis to determine the motions. For example, during the occurrence of the hazard 110, the projector 330 may display a virtual number pad 374 in the display area 230 on the wall 232. In another example, the projector 330 may project a single “help” button. An occupant in the infrastructure 101 may be harmed by the hazard 110 (e.g., burnt by the fire, smoke inhalation). In response, the occupant may move his/her finger sequentially over the virtual keys “9-1-1.” The detector 370 may detect the motion and transmit a detected signal 372, containing the sequence of “9-1-1,” to the PCA 320. The PCA 320 may relay the sequence to the server 140 via the wireless link 318 and/or the output link 312. The server 140, in response to receiving the sequence, may recognize the detected signal 372 as the emergency number for the police department, fire department, and/or emergency medical services. The server 140 may automatically contact the police department, fire department, and/or emergency medical services on behalf of the occupant and summon assistance to the occupant in the infrastructure 101. In some implementations, the server 140 may transmit location data (e.g., coordinate) to the authority to assist in locating the occupant. In certain aspects, the message notification device 900 may support two-way communication for allowing the occupant to communicate with the authority.

In some aspects of the present disclosure, the message notification device 900 may include a link that provides electrical energy to the components of the message notification device 900 (e.g., the PCA 320, projector 330, detector 370, etc.) and a separate link that provides one or more communication channel for uplink and downlink communications.

Referring to FIG. 10 , an example of a method 1000 for mass notification may be performed by the communication component 160, the hazard component 162, the direction component 164, and/or the server 140.

At block 1010, the method 1000 may receive an indication signal from a detector in an infrastructure, wherein the indication signal is transmitted by the detector in response to detecting a hazard in the infrastructure. For example, the communication component 160 of the server 140 may receive an indication signal from the detector 142 in the infrastructure 101. The detector 142 may detect a fire, earthquake, intrusion, active shooter, flood, carbon monoxide leak, or other events that may be dangerous to the occupants of the infrastructure 101. The detector 142 may send the indication signal in response to detecting the hazard 110.

At block 1020, the method 1000 may generate a plurality of messages, wherein the plurality of messages is associated with the hazard. For example, the hazard component 162 and/or the direction component 164 of the server 140 may generate the messages “Evacuate→North Exit,” “Evacuate←North Exit,” “Evacuate→West Staircase,” and “Evacuate←West Staircase.” The messages may include recommendations and/or directions for the occupant to safely exit the infrastructure 101 while avoiding the hazard 110. Some or all of the contents of the messages may be predetermined and/or stored in the server 140 and/or the repository 150. For example, the server 140 and/or the repository 150 may store the words/phrases “Warning,” “Lockdown,” “Stay,” “Indoor,” “Evacuate,” “Return to Room,” “Bar Door,” “North Exit,” “East Staircase,” and “West Staircase,” and the symbols “←” and “→.” Based on the analysis performed by the hazard component 162 and/or the direction component 164, the hazard component 162 and/or the direction component 164 may generate the messages “Evacuate→North Exit,” “Evacuate←North Exit,” “Evacuate→West Staircase,” and “Evacuate←West Staircase.”

At block 1030, the method 1000 may transmit the plurality of messages to a plurality of integrated notification devices, wherein each of the plurality of integrated notification devices includes a link that provides a communication channel with a server, a projector configured to emit light patterns, and a printed circuit assembly (PCA) connected with the link and the projector, wherein the PCA is configured to receive a message from the server via the link and cause the projector to project the message on a surface using the light patterns. The plurality of messages may be the same message or different messages with different messages being transmitted to different integrated notification devices. For example, the communication component 160 of the server 140 may transmit the messages “Evacuate→North Exit,” “Evacuate←North Exit,” “Evacuate→West Staircase,” and “Evacuate←West Staircase” to the integrated notification devices 120 a-1. The integrated notification devices 120 a, 120 b, 120 c may receive the message “Evacuate→North Exit.” The integrated notification devices 120 d, 120 e may receive the message “Evacuate←North Exit.” The integrated notification devices 120 f, 120 g, 120 h, 120 i, 120 j, 120 k may receive the message “Evacuate→West Staircase.” The integrated notification device 120 l may receive the message “Evacuate West Staircase.” In alternative implementations, the server 140 may transmit representations of the messages to the integrated notification devices. For example, if “Evacuate North Exit” is stored as message 5 in the integrated notification devices 120 a, 120 b, 120 c, the communication component 160 of the server 140 may transmit “message 5” to the integrated notification devices 120 a, 120 b, 120 c to indicate “Evacuate North Exit.”

Referring to FIG. 11 , an example of a method 1100 for displaying a message may be performed by the PCA 320 and/or the projector 330 of the message notification device 300.

At block 1110, the method 1100 may receive the message, from an alarm notification device via a link. For example, the PCA 320 may receive the message sent by the server 140 and/or the communication component 160 of the server 160 via the input link 316.

At block 1120, the method 1100 may, in response to receiving the message, cause a projector to project a light pattern displaying the message. For example, the PCA 320 may cause the projector 330 to display the message on a surface of the wall 232 in the display area 230.
